Extracted text: At least one of the answers above is NOT correct. Let f(x) -9. Find the open intervals on which f is increasing (decreasing). Then, determine the x-coordinates of all relative maxima (minima). click here to read examples. 1. f is increasing on the intervals 2. f is decreasing on the intervals none 3. The relative maxima of f occur at x = none 4. The relative minima of f occur at x попе Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2), (3,4), or the word "none". In the last two, your answer should be a comma separated list of ¤ values or the word "none". Hint: Note: You can earn partial credit on this problem.
